TROLLEY-STAN D.

Specification of Letters Patent.

Patented July 17, 1906.

Application filed October 8. 1905. Serial No. 281,143.

To aZZ whom it may concern.

Be it known that I, BRYAN MGMANAMAN, a citizen of the United States, residing at Wilkes-Barre, in the county of Luzerne and State of Pennsylvania, have invented new and useful Improvements in Trolley-Stands, of which the following is a specification.

This invention relates to trolley-stands, the object of the invention being to provide a strong structure of this character which is effective in operation and which has means whereby the trolley-wheel will be maintained in proper contact with the overhead wire or conductor, and should it accidentally jump therefrom means of a positive character are provided for preventing the abnormal elevation of the pole.

The invention includes other objects and advantages which, with the foregoing, will be set forth at length in the following description, while the novelty of the invention will be included in the claims succeeding said description.

In the drawings accompanying and forming a part of this specification I illustrate a simple form of embodiment of the invention which to enable those skilled in the art to make the same I will set forth in detail in said description.

In the drawings, Figure 1 is a side elevation of a trolley-stand involving my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a similar view of a base-plate.

Like characters refer to like parts through out the several fi ures.

The device inc udes in its make up a base, as 2. The base 2 is shown as consisting of a circular plate or disk adapted to be fastened in any suitable manner, as by several screws or bolts, to the top or roof of a trolley-car or like vehicle. The base 2 has a central circular aperture to receive the depending pivot of the standard 3, from which it will be understood that the standard is associated for turning motion with the base.

From the standard rise the complemental lugs 4, presenting together a fork to receive for swinging motion the socket members 5 and 6, a bolt, as 7, extending entirely through the lugs 4, serving as a convenient pivot for the two socket members 5 and 6. One of the socket members is bifurcated to receive the other, as will be clearly seen upon inspection of the drawings. Each lug 4 carries a selffeeding oil-cup, as 8, to supply lubricant to the journal portions of the bolt 7.

In the socket member 5 is set one end of the trolley-pole. The two parts may be united in any suitable wayfor example, by a screw-threaded joint. In the other socket member 6 is set a short rod, as 9. The socket member 6 receives the rod or plug 9 for sliding motion, as will hereinafter appear.

From opposite sides of the standard 3 below the lugs 4 extend in horizontal direction two pairs of projections or stubs, as 10 and 11. I provide two pairs of these stubs, so as to make the standard reversible, only one pair of the stubs or projections being in use at a time. In the drawings the projections or stubs 10 are shown as being in use. From these extend in an upward direction springs, as 12, two springs being on each side. The lower ends of the springs may be connected with the projections or stubs 10 in any desirable manner. For example, said projections may have eyes to receive hooks upon the lower ends of the springs. The upper ends of the springs are shown as connected by hooks and eyes with the trolley-pole or socket member 5 at longitudinally-separated points. Should the trolley-wheel (not shown) jump from the wire, the springs 12 will prevent the pole from swinging upward.

Between the rod 9 and the socket member 5 I show two braces, each denoted by 13, the opposite ends of the braces being connected to the respective parts in any desirable way. For example, the socket member and rod-are encircled by clamps to which the braces are connected, whereby the parts are removably related.

From the outer end of the rod 9 is flexibly suspended a weight, as 14, the oi'lice of which is through the agency of the intermediate arts to maintain the trolley-wheel (not sliown) in working contact with the overhead conductor.

Through the base-plate 2 vertically extend perforations opening into diametrically opposite and laterally-extending channels in the under side of the plate, the outer ends of the channels being located in the periphery of the plate. The perforations and channels serve for the passage of feed-wires for supplying the necessary current to the lamps within the car to light them.

It will be remembered that the socket member 6 has been described as receiving for sliding motion the rod or plug 9. Inclosed in said socket member 6 is a coiled push or protractile spring 15, the inner end of which bears against the closed inner end of said socket 6, while the opposite end thereof bears against the said rod or plug 9. The spring 15 is the main spring of the device and augments as one of its purposes the effect of the weight 14 in holding the trolley-wheel in contact with the overhead or feed wire. The spring acts in a yieldable manner against the plug or rod, and the latter in turn acts against the braces to apply an upward swing automatically to the socket member 5, which constitutes, in effect, or is really a part of the trolley pole. The weight and spring therefor transfer their force to the pole through brace means consisting in the present case of companion braces 15. The main spring automatically maintains the pole in proper relation with the overhead wire as said pole assumes difierent angular positions with respect to the car during the travel of the latter. To prevent the plug or rod from being pushed from place, I provide a stop, as 16, shown as a bolt carried by the socket 6 and extending through a longitudinal slot in said rod or block.

Having described the invention, what I claim is 1. In a trolley-stand,the combination with a base, a standard mounted for turning motion upon the base, a socket member, a second socket member, a pivot on the standard common to said two socket members, a plug carrying a pendent weight, fitted for sliding motion in one of the socket members, brace means extending between the plug and the first socket member, a spring in the second socket member acting against said plug, and spring means connecting the first socket member with the standard.

2. In a trolley-stand, the combination of a base, a standard mounted for turning motion upon the base, a socket member, a second socket member, a pivot 011 the standard common to the two socket members, a plug carrying a pendent weight, fitted for sliding motion in the second socket member and having a longitudinal slot, a pin extending through the second socket member and also through the said slot, a spring incased by the second socket member and bearing against the plug, brace means extending between the plug and first socket member, and spring means extending between the first socket member and the standard.

3. In a trolley-stand, the combination of a base, a standard mounted for turning motion upon the base, two socket members, a pivot on the standard common to said two socket members, a plug carrying a pendent weight, fitted for sliding motion in one of the socket members, brace means extending between the plug and the other socket member, and a spring acting against the plug.

4. In a trolleystand, the combination of a base, a standard mounted for turning motion upon the base, two socket members, a pivot on the standard common to said two socket members, a plug carrying a pendent weight, fitted for sliding motion in one of the socket members, brace means extending between the plug and the other socket member, and a spring acting against the plug, said spring being incased within that socket member with which the plug is directly associated.

5. In a trolley-stand, the combination ofa base, a-standard mounted for turning motion upon the base, a pole-carrying socket member, a second socket member, a pivot common to the two socket members, carried by the standard, a plug supported for sliding motion by the second socket member and carrying a pendent weight, a spring in the second socket member acting against the plug, brace means between the plug and the pole carrying socket member, and spring means between the pole carrying socket member and the standard.

In testimony whereof I havehereunto set my hand in presence of two subscribing witnesses.

BRYAN MOMANAMAN.
